Default Antec Tricool 120MM fans - noisy at times. Any fix?

I bought two of the antec tricool fans from fry's electronics for $15 a pop, and they seem to make a slight rocking/clicking noise. It coincides with the LED's blinking. Is there any way to get rid of this noise?

I noticed when I try them with my P4 motherboard, which runs hotter, its fan control feature cranks them up which makes the LED's stay on solid, and there is no clicking. When the system is idle, they go back down and start clicking and blinking again. My core 2 duo motherboard never gets hot enough to do this on the other hand. Is there any way to eliminate this clicking/blinking while they are in a low power state?

AFAICT a solution would be to disconnect these from the motherboard and give them a direct 12v line, but then that removes the dynamic fan control features of the motherboard which I would like to remain intact.

Well you have just said what the problem is, as with all LED fan when running at reduced power they turn hown the power which decreases the brightness of the LED and in some cases cuases electrical noise.

I would rather have some constant noise rather than intermittent. Only thing I can think of is to disconnect the LED wire.

On the SilenX fans I reviewed the 120mm and 80mm back in Jan of 2005. Both are still running 24/7 and all the LEDs are still burning.

Well, I actually didn't intend for it to be an LED fan, it was just the only 120MM fan they had when I was there buying my new case. I really don't care to have the LED's, because my case is hidden from view, and I prefer it that way.

I think I am going to stick with these tricool fans only I am going to find a non LED version. The reason I like these tricool fans is because that switch is pretty convenient. I can adjust the CFM willy nilly. The silenx fans you have to pick whether you want high CFM or low noise. I've had a silentx fan before, and wasn't impressed with that restriction.

Fry's electronics has a 30 day return policy so I can just wait until they have what I am looking for. I bought them B&M so its not as if I have to pay for any kind of shipping. For the time being I am going to just connect both of these to a direct 12v line so that they can draw as much power as they need. I have yet to see any of my temps get anywhere near critical even with these fans on their lowest settings.

best 120mm fans are the Nexus and Noctua fans. At least if you are looking for silent fans.

Well keep in mind there is a minimum level of quietness you can get with your computer, depending on what kind of hardware you have. WD raptor 150GB drives without the window operate at a very quiet 32dB most of the time (the raptor x drives make more noise, at about 47dB.) And this is just from the platters creating that high pitched hum, the clicking sounds of the heads are even louder.

Having any fans that operate at fewer bels than this is pretty much moot because you are still going to hear the noise from that hard drive anyways.

Between my PSU, my GPU, and my hard drives, they aren't going to add any appreciable noise. At least, not subjectively anyways.
With that considered, these tricool fans generally operate at about 30dB at the highest setting, and I am running them at something even lower than their lowest setting with the ability to dynamically adjust as needed, which is good for where I live since during the summer my room will easily reach 90F, and those low CFM fans just won't cut it.

See this page to put the bel/decibel system into better perspective:

http://www.glenbrook.k12.il.us/GBSSC...nd/u11l2b.html

A big thing with me living where I live is that I am trying to avoid producing much heat in the first place, because it really does drive up the utility bills here for the air conditioning. Therefore I do not overclock, (whereas before the P4 days I used to, but now it is just too uneconomical) and I do not buy more hardware than I need (e.g. an SLI setup which would produce tons of heat.) If it weren't for that, then I would probably consider nexus or panaflo fans. There is no such thing as a cooling system that gets rid of heat, it just dissipates it. Unless of course I had some kind of system to deliver the heat outside like most people have for their clothes dryer, but that is not a project I feel like messing with.

It's a very good thing that core 2 duo CPU's run much cooler than P4's as well. But it seems that these LED case fans were designed for a system that is really going to put extra juice in them to handle the heat issues. It just seems that I need to find some of these without the LED's, thats all.

Not having any issues with my Tri-Cools. On the low setting, they pull about as much air and are just slightly louder than the Silenx. They just have a different tone. My old Silenx fans varied from fan to fan. I moved to the Tri-Cools because the SilenX fans start to get louder as they age.

Experiment with BIOS settings and see if you can improve the tone of the fan. Also, you could try sharpening the leading edges of the fan blades. Sounds silly, but it sometimes helps. Heh.

I just replaced a RAID0 with two Seagate 80GBs with a Raptor 150. It is louder on seek, but the 10k spin is not anymore audible than two 7200s that are considered nearly silent. My system is not silent, but it is very quiet, overshadowed by the slightest background noises. With music playing downstairs, I brought my brother upstairs to check out my system and he was shocked that it was already running as he could not pick it out of the background.

Also, if you are not OC'ing, try undervolting your memory and CPU.

Seconded for the Noctua ones. Never tried a Nexus (although I heard they're really good), but the Noctua simply are the best fans I've ever tried. Amazing.

The tri-cool fans that came in my P180B used to click as well. They arent LED fans though. The clicking was definitely annoying but I think it went away over time because I don't notice it any more. I did move the fans around a bit though so that probably helped.

Also, the LED fan I stuck in the top of my case (I think its a thermaltake) is MUCH louder than any of the tri-cool fans. It makes an irritating whining sound even at the lowest speed setting and it isnt even a constant sound its a sort of fluctuating motor sound and it was really hard to get used to after having the nearly silent tri-cools in there for 4 months.

Woa check these fans out:

http://www.newegg.com/Product/Custra...82E16835185005
http://www.sidewindercomputers.com/scsf63cfms12.html

Fluid bearings...these are the same kinds of bearings that hard drives moved to in order to become quieter. Very nice airflow for the noise level. Just wish there was some way I could try before I buy. More airflow than I need and costs less than these tricool fans do.
